IMPROVEMENT IN CLOTQ'LQUTTING ATTACHMENTS FOR SEWING-MACHINES.

The Schedule referred to iriipqsnbetters Patent and making part of the name.

We WILLIAM EDGAR PRALL, of the city of Wash ing-Machincs, of whichthe following is. a speeiiicm.

tlon.

This invention consists in a scissor-like cutting device combined with the ordinary sewing-machine, and

operated as herein described, so that the operator can cut as well as sew cloth or othermatcrial.

In the annexed drawing, making a part of this specification,

Figure 1 represents a side view of our scissor-attachment, showing it applied tothe table of an ordivnarysewing-niacinne, having the hand-wheel above the table.

.by its rotation when brought in contact with the.

hand-wheel, the required vibrating motion to the leg E to cut the material.

To the leg D is attached a spring, I, which engages a pin or projection, J, on the leg E, and thereby causes .tiieleg E and its roller G to press against the peripheryfithe hand-wheel A.

loch the hand-wheel of the machine is set in motion the cutting edges of the scissors are rapidly opened and closed, and the operator needs but to draw the material along between the scissor-blades whereby the material is cut in a very rapid manner.

In order to disengage the scissors we employ the hinged hook K, or any similar device, by means of which the movable leg E can be held off the wheel A and prevented from operating whenever desired.

By means of a cap secured to the leg D, or to the table, the scissors may be covered and the material kept from contact with the scissors.

When the attachment is used with or applied to sewing-machines not provided with the hand-wheel A, or having said hand-wheel located in a position not convenient for attaching the scissors,-the movablc leg E may obtain its motion from any desirable part of the machine having a rotary or vibrating motion, and the said leg is consequently furnished with the required connection to obtain its motion.

Having fully described our invention,

What we desireto claim, and secure therein by Letters Patent, is-

The cutting-attachment, constructed as herein shown and described, when combined with and operated from the rotatingwheclor shaft of the ma-.

chine.
